2 claims. (or. 74-70 This invention relates to a starter mechanism and more particularly to a starter mechanism to be placed on a tractor that was originally sold without a starter mechanism.

There -are'many tractors still in use that were originally sold without starter mechanisms as original equipment. It is with the problem of equipping such a tractor with a starter mechanism that the present invention is involved.

i It is an object of the present invention, among others, to provide a starter mechanism for a tractor that can easily be adapted and mounted on a tractor; a starter mechanism that is simple in construction and operation, easy to operate and economical both in construction and operation; a starter mechanism that is long lasting and `durable in operation, requiring less repair and lost time in operation; a starter mechanism that is easy to operate, simple in design and easy of repair in case of breakdown; a starter mechanism requiring no special skill to mount-on a tractor;

and a starter mechanism that can be supplied at an economical price.

In carrying out the objects of the invention there is provided a starter mechanism for -attachrnent to a tractor having a supporting member on each side of the tractor and a main drive shaft for the tractor. A gear is attached to the main drive shaft of the tractor. A starter motor has a shaft extending from the starter motor and has a gear on the shaft extending from the starter motor. A housing member is attached to the starter motor and extends from the starter motor to cover the shaft extending from the starter motor. The starter motor has a shoulder on one end thereof against which the housing member abuts and bolts pass through the shoulder on the starter motor and are screwed into the wall of the housing member to attach the starter motor and housing member together. There is a slit in the outer circumference of the housing member of suiiicient length to form an opening to allow the outer portion of the gear on the main drive shaft to extend through the opening and mesh with the gear on the shaft extending from the starter motor. The starter mot-or and housing member are supported from the supporting members on each side of the tractor and a shield is attached at one end to a supporting member on the tractor which shield extends under and around the gear on the main drive shaft with the other end of the shield attached to the housing member and a bracket is mounted on the housing member to attach the housing member to the other supporting member on the tractor.

With the foregoing and other objects in View,"

the invention will be more fully described herewith and will be particularly pointed out in the claims appended hereto.

In the drawings,v wherein like symbols refer to like or corresponding parts throughout the sev-- eral views:

Figure 1 is a side elevational view of a tractor with the starter mechanism shown shaded and mounted on the tractor.

Figure 2 is a sectional view taken on the liner' in-Figure 1 which has two large wheels on the back'and two small wheels on the front, one of' which is shown at 2, so as to make three tracks when the tractor is in motion. The tractor has a power unitor'engine 3; Aa, radiator 4, steering column 5, fan =6,`fan belt 'I and exhaust discharge 8. The tractor has a pair of side supporting members 9 and Ill forming a framework for supporting the different portions making up the tractor. A main drive shaft II (Figure 2) is connected with the engine 3 and transmits power from the 'engine 3 to the rear wheels of the tractor I.

main drive shaft ,I I. tached to the main drive shaft I I and has openings drilled through the pulley I3 and gear I2 into which -openings bolts I4 are entered in order to attach the pulley I3 and gear I2 together. The main drive shaft I I can be separated so that the gear I2 can be placed over the main drive shaft II and holes drilled in the pulley I3 and gear I 2.

A starter motor I5 is a regular electric motor operable from a battery carried by the tractor and set into operation from a push button accessible from the drivers seat. The starter motor I5 has a shaft I6 extending therefrom which is thrown outwardly when the starter motor I 5 starts into operation. When the starter motor I5 stops, a spring I1 pulls the shaft I6 rearwardly toward the starter motor I5.

A housing member I8 extends from the starter motor I5 and covers the shaft I6. The starter motor I5 has a ange I9 surrounding one end thereof through which bolts 2E! pass and are screwed into the wall portion of the housing member I8 to attach the starter motor I5 and the housing member I8 together. The housing mem- A gear I2 is attached to and rotates with thel A fan belt pulley I3 is atf ber I8 has a slit 2| forming an opening through which the gear I2 extends to within the housing member I8. The shaft II has a gear 22 mounted thereon with which the gear I2 meshes when the starter motor I5 is operating. It can thus be seen that when the starter motor I5 is rotated, shaft I6 with gear 22 attached will be rotated and thrown outwardly so gear 22 meshes with the gear I2. The-geen I2; Wil-,ll be rotated, thus rotating main shaft II` which turnsover the motorl to start the same.

A shield 23 is connected at one end thereof to, the supporting member I of the tractor as.- by. bolt 25. The shield covers a portion of the front face of the gear I2 and extends. inwardly, to

protect the underface of the gears as the gear- I2 rotates. The other end of1 the shield; 2 3, is, attached to the housing member I8 in any suitable manner such as by bolts, welding etc. A bracket 24 is attached to the housing member I8 and provides: the Ineens` for.r atteehing the;E housing, member- La audi.heneethe-` Steiner-meter L5. and, heus:- ine; memberV |81 te-thefethensupportins member,.- 9.- of the tractor by a bolt 25.
